Hi, trying to figure out this mystery. First, the unit had a broken micro switch for the water dispenser. No problem replaced it and had water. Now, the ice dispenser is haywire. When the ice maker cycles to ice the ice tray water fills and water also comes out the front water dispenser on the door. I thought I had a bad solenoid. I tested them and applied voltage to each. They appear and sound like they are working. Why is water coming out the door dispenser. Is it possible I hooked up the solenoids wrong. It has three . One inlet and a dual set up for ice maker and water dispenser. One red solenoid, one purple and one green. The connectors are colored red,purple and white. is it possible that the water solenoid is sticking open allowing water to flow. I have very hard water here and wondering if the solenoid is sticking open. Any help is appreciated. I can't seem to find any wiring diagrams online.

You got something backwards. i no you have a three solenoid water valve.One solenoid on the plug in is smaller then the other two.So that should go to the smallest terminal on valve.the other two electrical plug in are same sizes.Did you remove any wires on valve is were on going .If not you have tubing problem.

I looked for a tech sheet but couldn't find one. Could you post a picture of the schematic? Some of these dual valve systems have a couple of diodes in the circuit. If one of the diodes shorts out, it will send power to both valves.
